Particle collecting device

Abstract

A particle connecting device includes a cage having a hub and a cover on each of two ends thereof. A handle is pivotably connected between the two covers and the two hubs. The cage is composed of multiple resilient wires which are bow-shaped, and the two ends of the resilient wires are respectively connected to two end pieces. Each hub includes pivotal portions which are pivotably connected to the corresponding end piece. The pivotal portions each include a hook to hook the cover. A shaft extends through the center of each of the hub and cover, and is pivotably connected to a respective lug of the handle in axial and radial directions.

What is claimed is: 
     
       1. A particle connecting device comprising:
 a cage having multiple connection units, each connection unit having two end pieces and multiple resilient wires that are arranged side by side, each end piece having a positioning hole, each end of the resilient wires of each connection unit being connected to one said end piece; 
 two hubs each having a disc which has an axial hole defined centrally therethrough, multiple pivotal portions formed on outside of the disc and located surrounding the axial hole, each pivotal portion having a hook which is resiliently and radially movable relative to the disc, each pivotal portion inserted into the positioning hole of one said end piece of one said connection unit, the end pieces connected to the two hubs, the resilient wires being arranged to form a chamber; 
 two covers each having a body which has a shaft hole defined centrally therethrough, multiple fixing holes defined in the body and located surrounding the shaft hole, the pivotal portions of the hubs respectively inserted into the fixing holes, each of the hooks hooking a periphery of the fixing hole corresponding thereto, the bodies covering up the end pieces; 
 a shaft extending through the axial hole of the disc and the shaft hole of the body corresponding thereto, the shaft including a flange formed on a first end thereof which is located opposite to the hub corresponding thereto and engaged with an inside of the hub, a receiving recess defined in a second end of each shaft, and a first locking hole defined centrally in the shaft, and 
 a handle having a handle body and two lugs which are formed on two ends of the handle body, a handle extension extending from a central portion of the handle, the two lugs located on two respective outsides of the covers, each lug having a pivot extending from an inside thereof which faces the cover, the pivot inserted into the receiving recess of the shaft corresponding thereto, the pivot having a second locking hole defined centrally therein, the second locking hole of the pivot located corresponding to the first locking hole of the shaft, a locking member extending through the first and second locking holes to connect the lug to the shaft. 
 
     
     
       2. The particle connecting device as claimed in  claim 1 , wherein each of the end pieces is a fan-shaped piece, and the end pieces are assembled to the hubs side-by-side. 
     
     
       3. The particle connecting device as claimed in  claim 1 , wherein the disc of each hub includes a tubular portion extending from the outside thereof, and the axial hole of the hub extends through the tubular portion. 
     
     
       4. The particle connecting device as claimed in  claim 3 , wherein the body of each cover includes a first stepped portion and a second stepped portion formed on an outside thereof, an outer diameter of the second stepped portion is smaller than that of the first stepped portion, the shaft hole of the body extends through respective centers of the first and second stepped portions, and the first stepped portion is engaged with the tubular portion of the corresponding hub to connect the body to the hub. 
     
     
       5. The particle connecting device as claimed in  claim 4 , wherein each of the lugs of the handle has a groove defined in the inside thereof, and the groove is engaged with the second stepped portion of the cover corresponding thereto. 
     
     
       6. The particle connecting device as claimed in  claim 1 , wherein each of the covers has a peripheral portion which is connected to an outer periphery of the body, and the peripheral portion covers a periphery of the end piece and the ends of the resilient wires of each of the connection units. 
     
     
       7. The particle connecting device as claimed in  claim 1 , wherein the shaft includes at least one restriction recess which is parallel to the first locking hole of the shaft, a pin extends from a distal end of the pivot of the lug corresponding thereto, and the pin is inserted into the restriction recess.
